(x + 10) cm
(x - 3) cm
The area of the rectangle is 48 cm².
Show that x satisfies the equation x2+ 7x - 78=0
Answer:
area a=lxb
48=(x+10)x(x-3)
48=x2-3x+10x-30
0=x2+7x-30-48
0=x2+7x-78
hence it is proved
The requried, we have shown that x satisfies the equation x² + 7x - 78 = 0.
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
The area of the rectangle is given by the formula:
Area = length x width
Substituting the given expressions for length and width, we have:
Area = (x + 10)(x - 3)
We are also told that the area of the rectangle is 48 cm², so we can set up the equation:
(x + 10)(x - 3) = 48
Expanding the left side using the FOIL method:
x² - 3x + 10x - 30 = 48
Simplifying:
x² + 7x - 78 = 0
Therefore, we have shown that x satisfies the equation x² + 7x - 78 = 0.

Pocahontas opens a savings account with $640 dollars that earns 3.9% interest per year not compounded. How much money to the nearest penny will Pocahontas have in 8 years
Given:
Principal value = $640
Rate of interest = 3.9% not compounded
Number of years = 8
To find:
The amount after 8 years.
Solution:
It is given that the interest is not compounded. It means, we need to find simple interest.
Formula for simple interest:
[tex]I=P\times r\times t[/tex]
where, P is principal, r is rate of interest and t is time in years.
Put P=640, r=0.039 and t=8.
[tex]I=640\times 0.039\times 8[/tex]
[tex]I=199.68[/tex]
So, the interest is $199.68.
Now, amount after 8 years is
[tex]A=P+I[/tex]
where, P is principal and I is interest.
[tex]A=640+199.68[/tex]
[tex]A=839.68[/tex]
Therefore, the amount after 8 years is $839.68.

Nitrosyl fluoride has the chemical formula NOF. Nitrogen has five valence electrons, oxygen has six, and fluorine has seven. Complete the
Lewis structure for this covalent compound.
Answer:
.. .. ..
o = N - F :
.. ..
Under the N just leave empty
Step-by-step explanation:
The complete lewis structure for NOF covalent compound is rewritten as: O=N-F
What type of bond is in NOF (Nitrosyl fluoride)?In a molecule of NOF, Oxygen is double bonded with Nitrogen. Nitrogen molecule of NOF is single bonded with flourine.
Rest of the valence electrons are not bonded.
Nitrogen's atomic number: 7, valence electron's count = 5Oxygen's atomic number: 8, valence electron's count = 6Florine's atomic number: 9, valence electron's count = 7Thus, with the above said description we will get:
.. .. ..
O = N - F :
.. ..
(double bond uses 2-2 electron of each atom).
Thus, the complete lewis structure for NOF covalent compound is rewritten as: O=N-F

Nate bought a new pair of shoes that were on sale for 25% off. If the shoes were $5 originally, what is the sale price of the shoes?
its proportions btw
Answer:
The sale price would be $3.75
Step-by-step explanation:
5*25%=1.25
5-1.25=3.75
the sale price of the shoes would be $3.75 because 5÷4=1.25 and 5-1.25=3.75, unless you are including tax. hope you get a good grade!

Answer:
Step-by-step explanation:
A circle has a diameter of 3 meters. Which statement about the circumference and area is true?
A comparison of the area and circumference is not possible since the area cannot be determined.
The numerical value of the circumference and area are equal.
The numerical value of the circumference is greater than the numerical value of the area.
The numerical value of the circumference is less than the numerical value of the area.
Using the area and the circumference of the circle, it is found that the correct statement is given by:
The numerical value of the circumference is greater than the numerical value of the area.
What is the area of a circle?The area of a circle of diameter d is given by:
[tex]A = \frac{\pi}{4}d^2[/tex]
What is the circumference of a circle?The circumference of a circle of diameter d is given by:
[tex]C = \pi d[/tex]
In this problem, we have that d = 3, hence:
[tex]A = \frac{\pi}{4} \times 3^2 = \frac{9\pi}{4} = 2.25\pi[/tex]
[tex]C = \pi \times 3 = 3\pi[/tex]
Hence the correct option is given by:
The numerical value of the circumference is greater than the numerical value of the area.

7/2x -3(5x -1/2)
Answer:
Step-by-step explanation:
Original equation:
7/2x - 3(5x - 1/2) = ?
Use distributive property for the parentheses
-3 · 5x = -15x
-3 · (-1/2) = 3/2 or 1.5
Plug these values into the equation
7/2x - 15x + 1.5 = ?
Combine like factors
-11.5x + 1.5 = a (a = answer)
The equation with fractions:
-11 1/2 + 1 1/2 = a
